Italy operates one of Europe's most established mandatory e-invoicing systems. Structured electronic invoicing is required for domestic B2B and B2G transactions, with invoices exchanged through the national Sistema di Interscambio (SdI).
The B2B mandate has been in place since 2019 and has subsequently been extended to cover businesses that were initially exempt. As a result, electronic invoicing is now the standard method for exchanging invoices between businesses established in Italy.
